This is contrast to a spacecraft' s main engine, which is only capable of providing thrust in one direction, but is much more powerful. RCS systems often use combinations of large and smaller (vernier) thrusters, to allow different levels of response from the combination. An RCS system is capable of providing small amounts of thrust in any desired direction or combination of directions. High Quality Content by WIKIPEDIA articles! Its purpose is attitude control and steering. A reaction control system, abbreviated RCS, is a subsystem of a spacecraft. An RCS is also capable of providing torque to allow control of rotation (pitch, yaw, and roll).

|Underactuated Mechanical Nonminimum-Phase Systems. Analysis and Control Книга по Требованию Philippe M. |
Two-link underactuated mechanical systems without friction are shown to be nonminimum phase for those outputs that i) correspond to an arbitrary combination of the coordinates, and ii) are small-time locally controllable. On the control side, the forces present in these systems are separated into two categories, namely the actuator forces (direct effect of the input), and the state-dependent forces (integral effect of the input) such as gravity, Coriolis, centrifugal and possibly aerodynamic forces. The first scheme neglects the direct influence of the input, leading to a minimum-phase, flat approximation. The second strategy does not neglect the nonminimum-phase part but rather transforms it into a delay. These schemes are illustrated on a two-degree-of-freedom helicopter termed the Toycopter. In this system, the aerodynamic force is manipulated by changing the propeller rotation speed while maintaining the angle of attack constant. This thesis establishes the formal link between nonminimum phase and underactuation and proposes suitable control techniques. Underactuated mechanical systems have fewer independent actuators than the number of degrees of freedom.
|Database System with Efficient Security Enforcement. A Fine-Grained Access Control Approach Книга по Требованию Huaxin Z. |
A well-rounded yet efficient security mechanism would make a database product eligible for high profile government contracts and new markets in the financial sector, and make it trustworthy among many third party applications that are likely to be built on top of it. This book reviews traditional database paradigm and proposes architectural changes to improve database performance under modern security requirements.
